Rise and start to rotate, and move into the stage the first groove part 66 from the second groove part 68 at roller 102, only
The rotary motion on the direction of arrow D2 of second clamp arm 16 is stopped.
Now, the align member 44 being arranged on the second clamp arm 16 engages with the draw-in groove 42 of body 12, thus in clamping
Time, the second clamp arm 16 is positioned at predetermined stop position.
It addition, under the driving effect of driver element 18, block 94 declines further, thus one end of the first clamp arm 14
Side is pressed further via link arm 104 on the direction away from the second clamp arm 16.Meanwhile, the first clamp arm
The clamping part 70 of 14 is rotating around the first arm pin 46 on the direction (direction of arrow D2) of the second clamp arm 16.
Therefore, a sidewall 116 of the second framework W2 is towards the second clamp arm 16 side, i.e. be extruded towards the first framework Wl side
And deformation.
On the other hand, recessed along first extended in vertical direction in the cam groove 64 of gusset piece 56 due to roller 102
Slot part 66 moves down, close to the first clamp arm 14 or away from the first clamp arm 14 direction lifting force not via
Gusset piece 56 is applied in the end side of the second clamp arm 16, and the rotation of the second clamp arm 16 is completely stopped.
Additionally, by making block 94 decline, as shown in Figure 10, the first clamp arm 14 further rotates, and the first clamping
The clamping part 70 of arm 14 is upper mobile in the direction (direction of arrow D2) close to the second clamp arm 16 side, thus the second frame
The sidewall 116 of frame W2 mutually presses and deforms thus close to each other, and the sidewall 116 of the second framework W2 abuts the first framework
The sidewall of Wl, and cause clamped condition, under this clamped condition, clamping is when the sidewall of workpiece is almost parallel
(the seeing Fig. 9) completed.
